多功能控件

CGridListCtrlEx 非常好用的扩展库

可编辑

m_ctrl_list_geometric_coeff.SetExtendedStyle(m_ctrl_list_geometric_coeff.GetExtendedStyle() | LVS_EX_DOUBLEBUFFER | LVS_EX_GRIDLINES | LVS_EX_FULLROWSELECT |
		LVS_EX_SUBITEMIMAGES);
{
    CGridColumnTrait* pTrait = NULL;
    CString colsName[] = {
        L"编号",L"名字",L"描述",L"数值"
    };
    for (size_t i = 0; i < 4; ++i)
    {
        if (i > 0)
        {
            pTrait = new CGridColumnTraitEdit;
        }
        else
        {
            pTrait = new CGridColumnTrait;
        }
        m_ctrl_list_geometric_coeff.InsertColumnTrait(int(i + 1), colsName[i], LVCFMT_LEFT, 100, i, pTrait);
    }

LVN_ITEMCHANGED

```

## 常用代码

```c++
m_wndList.Create(WS_CHILD | WS_VISIBLE | LVS_REPORT | LVS_SHOWSELALWAYS, CRect(0, 0, 0, 0), this, IDC_FRM_FILE_LIST);//|LVS_SINGLESEL
m_wndList.SetExtendedStyle(m_wndList.GetExtendedStyle() | LVS_EX_DOUBLEBUFFER | LVS_EX_GRIDLINES | LVS_EX_FULLROWSELECT |
    LVS_EX_SUBITEMIMAGES);//LVS_EX_ONECLICKACTIVATE||LVS_EX_TRACKSELECT
//::SendMessageW(m_wndList.m_hWnd,LVM_SETHOVERTIME,0,1);

m_wndList.InsertColumn(0, TEXT("Name"), LVCFMT_LEFT, 400);
m_wndList.InsertColumn(1, TEXT("Ext"), LVCFMT_LEFT, 130);
m_wndList.InsertColumn(2, TEXT("Size"), LVCFMT_LEFT, 80);
m_wndList.InsertColumn(3, TEXT("Date"), LVCFMT_LEFT, 100);

m_wndList.SetColumnWidth(0, LVSCW_AUTOSIZE_USEHEADER);
if (m_wndList.GetColumnWidth(0) < 200)
{
    m_wndList.SetColumnWidth(0, 200);
}
m_imageList.Create(16, 16, ILC_COLOR24, 7, 7);
m_wndList.SetImageList(&m_imageList, LVSIL_SMALL);


BOOL CDlgIconList::FillList(HWND hwnd)
{
    // Clear the list before we start
    //	ListView_DeleteAllItems(hwnd);

    CDevHelperApp* pwnd = (CDevHelperApp*)AfxGetApp();
    ListView_SetImageList(hwnd, pwnd->m_hLarge, LVSIL_NORMAL);

    // Get number of icons in system image list
    count = ImageList_GetImageCount(pwnd->m_hLarge);

    LVITEM lvitem;
    TCHAR ach[20];
    // add to list
    for (int i = 0; i < 10; ++i)
    {
        wsprintf(ach, TEXT("%d"), i);
        lvitem.mask = LVIF_TEXT;
        lvitem.iItem = i;
        lvitem.iSubItem = 0;
        lvitem.pszText = ach;
        ListView_InsertItem(m_wndView.m_hWnd, &lvitem);

        m_wndView.SetItemText(i, 1, TEXT("1"));
        m_wndView.SetItemText(i, 2, TEXT("2"));
    }
    return TRUE;
}

//从扩展名中获取图标信息 
SHFILEINFO shfi;
memset(&shfi, 0, sizeof(shfi));
if (0 == SHGetFileInfo(TEXT("*.rxs"), FILE_ATTRIBUTE_NORMAL, &shfi, sizeof(shfi), SHGFI_ICON | SHGFI_USEFILEATTRIBUTES))
{
    AfxMessageBox(TEXT("Failed"));
}
int idx = m_imageList.Add(shfi.hIcon);
if (0 == SHGetFileInfo(TEXT("*.doc"), FILE_ATTRIBUTE_NORMAL, &shfi, sizeof(shfi), SHGFI_ICON | SHGFI_USEFILEATTRIBUTES))
{
    AfxMessageBox(TEXT("Failed"));
}
m_imageList.Add(shfi.hIcon);
m_wndList.InsertItem(1, TEXT("dd"), idx);
m_wndList.InsertItem(2, TEXT("test"), idx + 1);

InsertItem
Return Value
The index of the new item if successful or - 1 otherwise.
//== == == == == == == == == == == == == == == == == == == == == == == == == == == == == == == ==
BOOL DeleteItem(int nItem);
Return Value
Nonzero if successful; otherwise zero.
//== == == == == == == == == == == == == == == == == == == == == == == == == == == == == == == ==
插入项带图标
nt idx = m_imageList.Add(shfi.hIcon);
m_wndList.InsertItem(1, TEXT("dd"), idx);

双击事件

使用向导添加NM_DBLCLK即可

...
ON_NOTIFY(NM_DBLCLK, IDC_LIST1, &CTradeQuery::OnNMDblclkList1)
END_MESSAGE_MAP()

afx_msg void OnNMDblclkList1(NMHDR *pNMHDR, LRESULT *pResult);

void CTradeQuery::OnNMDblclkList1(NMHDR *pNMHDR, LRESULT *pResult)
{
	LPNMITEMACTIVATE pNMItemActivate = reinterpret_cast<LPNMITEMACTIVATE>(pNMHDR);
	// TODO: Add your control notification handler code here


	*pResult = 0;
}

删除一行/多行

m_ctrl_list.DeleteItem(nItem);

// 多行删除
while (m_ctrl_list.GetNextItem(-1, LVNI_ALL | LVNI_SELECTED) != -1)
{
    int nItem = m_ctrl_list.GetNextItem(-1, LVNI_ALL | LVNI_SELECTED);
    m_ctrl_list.DeleteItem(nItem);
}

删除列

inline void CMRLGaugerProgramerDlg::deleteAllColumns()
{
	int nColumnCount = m_list_data.GetHeaderCtrl()->GetItemCount();

	// Delete all of the columns.
	for (int i = 0; i < nColumnCount; i++)
	{
		m_list_data.DeleteColumn(0);
	}
	m_list_data.DeleteAllItems();
}

添加一行

++nItem;
int curItem = m_ctrl_list_geometric_coeff.InsertItem(nItem, utils::format(100, L"%d", nItem).c_str());
m_ctrl_list_geometric_coeff.SetItemText(curItem, 1, utils::format(100, L"k%d", nItem).c_str());
m_ctrl_list_geometric_coeff.SetItemText(curItem, 2, utils::format(100, L"Geom. Coeff.%d", nItem).c_str());
m_ctrl_list_geometric_coeff.SetItemText(curItem, 3, L"0.00");

遍历

//Get all selected item
POSITION pos = m_list.GetFirstSelectedItemPosition();
CString str;
DWORD dwID = 0;
if (pos == NULL)
{
    AfxMessageBox(TEXT("No item selected"));
}
else
{
    while (pos)
    {
        // if delete item need this
        //pos = m_list.GetFirstSelectedItemPosition();
        int nItem = m_list.GetNextSelectedItem(pos);
        strTmp.Format(TEXT("item %s selected"), str);
        dwID = m_wndList.GetItemData(nItem);
        str = m_wndList.GetItemText(nItem, 0);
    }
}

获取字段文字

CString str;
str = m_ctrl_list.GetItemText(pNMListView->iItem, 7);

获取列数量

m_ctrl_list_geometric_coeff.GetHeaderCtrl()->GetItemCount();

获取保存的 data

POSITION listPos = m_ctrl_list.GetFirstSelectedItemPosition();
if (listPos == NULL)	return;
int itemData = m_ctrl_list.GetNextSelectedItem(listPos);

可编辑列表框

void CfireShanghaiYongTianEF_01ConfigDlg::OnNMDblclkList1(NMHDR *pNMHDR, LRESULT *pResult)
{
	LPNMITEMACTIVATE pNMItemActivate = reinterpret_cast<LPNMITEMACTIVATE>(pNMHDR);
	m_ctrl_list.OnListEdit();

	*pResult = 0;
}

m_list_car.SetExtendedStyle(m_list_car.GetExtendedStyle() | LVS_EX_DOUBLEBUFFER | LVS_EX_GRIDLINES | LVS_EX_FULLROWSELECT |
    LVS_EX_SUBITEMIMAGES);
